FARE SUMMARY (USD):
Total: $177.60

US offered a similar fare ORD-PHX-PDX RT for $200 all in (~4cpm).
Same day run is possible on Saturdays.

UA has the same price of $178 on Saturdays only until 1 March, but less useful -- 3 nights minimum, it seems. Non-stop ORD-PDX, so only 3478 EQM at $0.051/EQM. Too bad.
